Nongestational ovarian choriocarcinoma (NGOC) is a sporadic and aggressive malignant germ cell tumor, with fewer than 100 cases reported in the literature. We present the case of a 28-year-old woman diagnosed with NGOC, who underwent fertility-sparing surgery and adjuvant bleomycin, etoposide, and cisplatin chemotherapy, followed by a recurrence managed with the second-line chemotherapy and radiotherapy. This report highlights the diagnostic challenges, unique β-human chorionic gonadotropin profile, disease course, and treatment response.
